Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Examples

Referring to fig. 1 and 2, a front chassis structure includes a front chassis; the front base is provided with a rainproof structure for preventing rainwater from entering the motor through the front base.

Referring to fig. 1 and 2, a front frame structure includes a front frame on which a rain-proof structure is provided.

The rain protection structure may be implemented in various ways known in the art, including but not limited to an umbrella-like rain protection structure, etc.

Referring to fig. 1 and 2, the cross-section of preceding frame is circular structure, rain-proof cover 1 is the loop configuration, and the cover is established on the preceding frame outside, and rain-proof cover upside 2 is connected with the upper portion in the preceding frame outside, and rain-proof cover downside 3 extends downwards from preceding frame outside upper portion to form rain-proof cover structure.

Optionally, the rain-proof structure is integrally formed with the front frame.

Referring to fig. 1-4, the cross section of the front frame is a circumferential structure, a plurality of strip-shaped ventilation slots 4 arranged in parallel are uniformly distributed on the circumferential surface of the circumferential structure, and the lower side 3 of the rain cover extends downwards from the upper part of the lower side of the front frame to the outer side of the strip-shaped ventilation slots to cover the strip-shaped ventilation slots, so that rainwater is prevented from entering from the upper parts of the strip-shaped ventilation slots.
